ARMA can be quick. I have a mission up on the workshop that makes it basically Battlefield CP style gameplay with tickets and what-not, but you get to use the gnarly weapon physics and such of the milsim. King of the Hill is basically that, but much more thought out than what I made and people actually play it online.

ARMA is first and foremost a sandbox toolset. It can be whatever you want it to be, if you mess with the editor.

But also: The TTK in ARMA has a really wide range depending on weapon, distance, where you hit, and the fact that the game is jank as fuck so you can literally survive a tank shell sometimes.
